I never said anything about FPGAs though. If you are telling me how microcode might be useful in overcoming limitations of FPGAs, I’m not sure what relevance that has to most microprocessors, which aren’t implemented as FPGAs
- geocar 4y agoNo, but they're a useful target for Verilog, and this limitation is shared by any hardware compute/circuit (I had hoped that would be obvious from the description)
- skissane 4y agoYou can implement a CPU completely with random logic, zero microcode - it has been done before. Yes you do end up needing something like extra registers to hold control state - but that’s not microcode
